This would also be my next choice. Just pull the gas lines off the carb and crank it over. If fuel shoots out you have eliminated the fuel pump to the tank. Then you get to start cleaning carbs, and this means completely disassemble it and clean the crap out of it.Originally posted by Luke
[br]Check to see that you fuel pump is working. ie: pulse line still connected and pump is moving fuel when you pull her over.
The line from the crankcase to the fuel pump is an impulse line. Part of the time, it's under vacuum (when the piston is going up). Part of the time, it's under pressure (when the piston is going down). Part of the time, it's neutral (at top and bottom of the stroke). The pressure/vacuum cycle causes the diaphram in the fuel pump to move back and forth, and that's what pumps the fuel.Originally posted by rev500ss
wouldn't the crank seals be ruled out if the fuel pump is working? if the seals are bad there won't be enough vacuum to the fuel pump for it to pump fuel.
